To all whom it may concem:

Be it known that I, Gnono SoHwAn oH, a

subject of the Emperor'of Germany, resid 'ing at 10 Giesebrechtstrass Charlotten-Q burg, Germany, have invented a certain-new and useful Regulating Device for Gas-'Supply Plants, of which thefollowing isa specification] 3 The supply of gases and gas mixtures, for example exhaust gases from furnaces, aciduous vapors, air saturated with dust and the like is generally effected in such a manner that the current of gas to be supplied is passed through a second gas or-air current. To provide these plants for various operations, regulating devices are necessary. Regulation is required for example, when the quantity of the gases to. be delivered or the resistance, which they meet, varies. The means hitherto employed in the regulation of such plants consists in varying the cross section of the aperture, from which the drivingjgas passes to mix with the driven 'gas. Such devices however do not suffice for large requirements, since to obtain' a favorable efliciency it is not only necessary to regulate the outlet aperture for the driving gas, but it is also necessary to simultaneously regulate the outlet aperture through which the mixture obtained passes, and the regulations of both cross sections must be effected simultaneously in such a manner that the two cross sections are operated to COIltlIlll.

ously' correspond to the working capacity.

The object of this invention is to provide such a regulation by means of a regulating body of such a shape that the two cross sectionsare enlarged or diminished according to its adjustment.

The invention is illustrated in the accompanying drawing. I

a is the pipe for the gases to be supplied, 6 is the pipe for the driving gas which leaves at c, where itflmixes with the gases passingthrough a. The mixture then passes through the opening d into the pipe 6 from which it is conducted farther. The regulation of the two cross sections 0 and'd is effected by regulating body 9 which is operated to adjust the cross sections by any suitable means such for example as a rope,

chain or the like 7 connected to a winch. The regulating body 9 has its length and cross section of such dimensions that in every position of the body g there is a correspondin tions' '0" an In Figure 1 the body 9 is shown of such construction that. on diminishing the cross section a by loweringt-hebody 9 there is a corresponding decrease in size of the cross section a.

InFig. 2 the regulating body is of such construction that a decrease in size, of the cross section 0 by lowering the body. g corresponds to a simultaneous increase in size of the cross section at which is often necessary.

Figs. 8-8 show various constructional forms of regulating body as rcquiredafor various uses. By mean of some of these forms it is possihle to rapidly vary the size of the opening 0 while the opening (5 isva-- regulation of the two cross 'secried very slowly. In some cases this is just the reverse. a

It is essential according to this invention that the shape of the regulating body is such that. the regulation of the cross sections 0 and d can be efiected simultaneously and in any relation to one another according to the circumstances of operation.

What I claim as my invention and desire to secure by Letters Patent is:

In gas supply plants the combination of a' gas inlet pipe, an inlet pipe for the driving gas located within the gas inlet pipe, a mi?- lng chamber in w ich the inlet pipes terminate, a common 0 tlet pipe for the gas mixture and means for simultaneously controli ling the area of the inlet pipe for the driving gas and that of the outlet pipe, consisting of a tapered body disposed within the mixing chamber and projecting into the inlet pipe for the driving-garland the outlet plpe.

In testimony whereof I have hereunto.

signed my name to this specification in the presence of two subscribing witnesses.
